We acknowledge the efforts of Athena Ganchorre during the first year developing and teaching the course and developing the first version of the outcome assessment instrument. We thank Susan Jorstad, Bruce Patterson, Ted Weinert, Angel Pimentel, and Ramin Yadegari for their feedback on outcome assessment items and their willingness to administer the assessment to their students. Thanks to Carol Bender, Joe Watkins, and the rest of the BioMath community at the University of Arizona for supporting a cross-departmental culture and conversation about integrating mathematics and biology. We also thank Molly Bolger for her input throughout development of the course and outcome assessment, and Katie Southard for her contributions as the teaching assistant and so much more early in course development. Finally, we thank the organizers of the Mountain West Summer Institute at the University of Colorado, Boulder: many of the strategies presented at the institute were instrumental in building our course. This work is supported by a grant to the University of Arizona from the HHMI (52006942).
